Abstract:
To improve water splitting efficiency and enhance energy utilization, it is crucial to develop catalysts with excellent activity, long-term stability, and low cost. In this study, we synthesized a three-dimensional nanostructured amorphous CoMoP/NF bifunctional catalyst for both the hydrogen evolution reaction (HER) and the 5-hydroxymethylfurfural oxidation reaction (HMFOR), using a sacrificial template method. Benefiting from element doping regulation and morphology control, CoMoP/NF exhibited outstanding catalytic activity. Notably, in an electrolytic water system coupled with HER and HMFOR, a cell voltage of only 1.5 V was required at a current density of 20 mA cm-2, approximately 189 mV lower than that of a traditional water electrolysis system. This study presents a novel energy-saving method for hydrogen production through the HER/HMFOR electrolysis system.

The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
